| Outline of Final Research Achievements |
(1) RGS1 is a protein necessary for the structure of lymphoid tissues.(2) This study focuses on the RGS1 expression in hematological neoplasia, with focus on the analysis of RGS1 in the Diffuse Large B-cell Lymphoma (DLBCL), Follicular Lymphoma (FL), MALT Lymphoma, other small B-cell lymphomas and Hodgkin Lymphoma. The immunohistochemical expression of RGS1 was variable. Immunohistochemical expression of RGS1 was associated with the prognosis of the patients. For example, high RGS1 expression associated with poor prognosis in DLBCL and FL. In addition, a correlation between RGS1 and tumor immune microenvironment was created.(3) The gene expression analysis of Diffuse Large B-cell Lymphoma gene was also performed and the relationship of RGS1 with other relevant clinicopathological markers was assessed.(4) The gene expression analysis was also analyzed by Artificial Intelligence.(5) Immunostaining was also analyzed by Artificial Intelligence.

RGS1は免疫システムの正しい機能に必要なタンパク質です。 RGS1は免疫系のいくつかの腫瘍であると分析しました。 RGS1がいくつかの腫瘍で可変的に発現されることを見出した。RGS1の発現がいくつかの腫瘍の患者の予後と相関していることを発見しました。 タンパク質発現レベルと遺伝子発現の分析を行いました。 分析は従来型であり、人工知能でもありました。 患者の予後と相関するため、このマーカーは重要です。 リンパ系腫瘍の診断時に、このマーカーをマーカーの診断パネルに含めることができます。 このマーカーは薬物でターゲットにできます。
